WATER-CLOSET.

Patented June19, 1906.

To all whom it may concern.- I

Be it known that I, BERNARD M. DRAWE, a citizen of the United 'States,residing at Sandusky, in the county of Erie and State of Ohio, haveinvented a certain new and useful Im rovement in Water-Closets, of whichthe fo lowing is a full, clear, and exact description, reference beinghad to the accompanying drawings.

The object of this invention is to provide an efficient water-closetwhich may be operated directly by the pressure in the main.

The invention comprises mechanism whereby a simple operation of a leveror other suitable release initiates means which automatically open agate, allowing the water to siphon the bowl. 'An auxiliary jet isprovided at the base of the bowl to augment the siphoning action. Theseand other features are comprised within the invention, which may be mostconveniently summarized as consisting of the construction andcombination of parts hereinafter more fully explained, and definitelyset out in the claims.

. In the drawings, Figure 1 is a vertical longitudinal section throughthe closet. Fig. 2 is a side elevation thereof, partly broken away. Fig.3 is a side elevation on the side opposite Fig. 2 Fig. 4 is a verticalsection on the line 4 4 of Fig. 3 looking to the right. Fig. 5 is ahorizontal section substantially on the line 5 5 of Fig. 1. Fig. 6 is ahorizontal section on the line 6 6 of Fig. 1, showing also the baseqofthe structure. Fig. 7 is. a detail in horizontal section on the line 7-7 of Fig. 4.

The same letters of reference designate the same part in each figure.

As shown in th drawings, the bowl, base, and the various chambershereinafter described may be made of one'-pieceas castiron or porcelain,for example-while the gate mechanism is a self-contained structureremovable therefrom. Thestationary part A includes the base-plate a, thesides a, the front a", the bowl of, having a rolled-over upper edge awhich supports the seat. (Not shown.) At the base of the bowl apassageway a leads upward beneath the wall (1 of the bowl, over adiaphragm a and then downward at a between the diaphragm a p and thefront wall a. into the passage-way a". The exit from the passage-way aleads bel sage-way b, which, as stated, is carried by the separate gatemechanism B.

- In normal position the exit is closed by the curved gate 1), whichengages at its lower end with the base-plate b and near its upper endwith the member 11 which forms a tlght connection with the lower portionof the bowl.

At its upper end the gate is rigidly connected 7 with a ucket I), thiswhole gate structure being pivoted at b on the upper side of the wall I)of the discharge passage-way.

On one side of the structure a tubular passage-way C leads from the benda to a pocket a. directly over the bucket, while on the o posite side apassageway D leads from tl fe chamber a (which has valved communicationwith the main, as hereinafter explained) to the pocket at at the base ofthe bowl.

' The purpose of the particular features of construction above describedcan be best un- 'der'stood from an explanation of the flushingoperation. In normal position the water in point of the dia hragms a andc When it is desired to flusthe bowl, water is admitted by the operationof the valve H, as hereinafter explained, into the chamber a, from thebowl stands on a level with the meetingwhence it flows into the openinga and thence into the passage-way a in the rolledover edge a at theupper end of the bowl.

The water continues to flow from this source. 7

until the passage-way a is entirely filled, as

well as the space between the diaphragm a I and the front wall (1, thewater rising high enough in these places to enter the upper end of thetubular passage-way O. Thereupon water flows through this pipe 0 intothe 1 pocket a and thence into the bucket 6 until Q such bucket is moreor less nearly full, whereupon the weight of the water in the bucketcauses it to-swing downward, raising the gate b and releasing the waterin the bowl and the passage-ways a and a, which thus goes into thedischar e-o ening with arush, effectively siphoning t e owl. During thesiphoning water from the chamber a passes by the ipe D into the pocket aat the base of the bowl and is discharged diagonally u ward through aninclined opening a, an thus flows up along the diaphragm a efiectivelyboosting or; augmenting the flushing operation.

I At the beginningof the flushing operation 4 the bucket 12 is swungdown into its lowermost position, thus causing a pin 1) on the valve toimpinge against the wall b opening this valve and releasing the watertherein, which 5 passes through the opening I) into the dischargepassage-way. The valve-openmg b is made of such size that the desiredinterval of time elapses after the bucket has swung down before itbecomes sufficiently empty to 10 return. After the bucket has emptieditself the gate b swings back by gravityinto the normal position, thusclosing the exit. A hole I) is made through the plate I) of the bucket,

so that water will remain on the front side of the bucket and retard itsdownward operation.

It now remains to describe the manuallyoperated mechanism for turning onthe water and the automatic arrangement which results in its being shutoff at the proper time.

The operation is initiated in any manner desired. As shown in thedrawings, a hand-lever E is provided for the purpose. This lever ispivoted to the frame on a rock-shaft which I 2 5 carries an internal armE, extending through a vertical rod F. Thus when the hand-lever israised this rod is raised. The rod is guided in the chamber a and at itslower end passes I through a lever G, which is connected with the stem hon the main valve H. The bonnet I-I, surrounding this valve, isconnected with the water-main. When the rod F is raised, the disk f onthe lower end thereof engages the lever G and swings it to lower the vave H, thus opening communication with the water-main, whereby water isadmitted to the chamber a. In the above-described movement the disk f onthe rod F engages and passes above the spring-finger j, whereby thevalve is held open, so that the operators hand may be removed from thelever E as soon as it is raised. The valve H being held open, water isadmitted into the chamber a, and from thence some of it passes outthrough the opening a into the outside pipe D, furnishing theboosting-jet through the opening a into the base of the bowl, as hereinbefore explained. The raising of the rod F causes the diaphragm f,carried thereby, to pass above the opening a, leading to the annularpassage way a, wherefore Water is admitted to such passage-way and flowsfrom thence into the bowl, and after it has reached the proper height inthe bowl and in the exit 55 passage-ways therefrom it flows back throughthe outside pipe 0, as hereinbefore explained, into the bucket. When thefilled bucket tips, it engages a rod j, depending from an arm 7' rigidon a rock-shaft which carries the spring-arm j". This movement rocks thes aft, so that the spring-arm j releases the disk f but just precedingsuch release a second arm f, carried by the rock-shaft, engages beneatha projection g on the lever G and 65 holds it elevated. The flow ofwater thus continues until the bucket swings back into normal position.In this movement the rod j is again engaged to swing the rock-shaft tocause the fingers j and j to return to normal position. In this movementthe finger j swings idly above the disk f (which when released droppeddown below the path of the fmger,) and the finger j releases theprojection g, thus allowing the valve to close, which it does gradually,the disk f on the rod F pre- 7 5 venting too sudden movement. Therockshaft is carried by a suitable stufiing-box or similar member j,while to prevent the leakage of sewer-gas around such rod the rodcarries a cup j which catches water leaking around the rod, and thusmakes a water seal.

A removable plate K is secured to the side of the casing op )osite theelbow of the admission-pipe. The removal of this elbow and this plateallows suflicient access to the inte- 8 5 rior for the purpose ofinstalling and adjusting the arts.

It wi 1 be seen that the operating mechanism for the gate is entirely onthe sewer side thereof and that there is no mechanism in the passage-waybetween the bowl and the gate, so that when the gate is open there is anunobstructed conduit to the sewer. This is an important point, as itprevents the collection of waste matter on the forward side of 5 thegate. The water seal in the cup j prevents any sewer-gas from passing upinto the chamber a, while any gas which passes into the chamber a isprevented by the water in the bend of the pipe C from entering the bowl.The water normally standing in the bowl above the lower end of the walla forms the usual seal at this point.

The positive gate across the discharge-pipe besides being useful in mostinstallations in barring the sewer-gas from the bowl is espe cialladvantageous when the fixture is used ons pboard, where the gateprevents water swashing up the discharge-pipe from backing into the bowland spattering therein, as frequently happens with many fixtures.
